The slotting machine is actually a vertical planer, which belongs to the same category as the bull’s head planer in terms of structural principles. The linear reciprocating motion of the inserting knife in the vertical direction with the ram is the main motion, and the intermittent motion of the workpiece in the longitudinal, transverse and circumferential directions is the feed motion. The production efficiency of the slotting machine is low, the surface roughness Ra of the machined surface is 6.3-1.6 microns, and the perpendicularity of the machined surface is 0.025/300 mm. The main parameter of the slotting machine is the maximum slotting length.
See lessThe main purpose is: it is used for processing inner keyway or spline hole in single or small batch production. It can also process flat, square or polygonal holes, etc. It is often replaced by milling machine or broaching machine in mass production.
The main parameter of the broaching machine is the rated tension.
Broaching
A machine tool that uses a broach as a tool to machine through holes, planes and shaped surfaces of workpieces. Broaching can obtain higher dimensional accuracy and smaller surface roughness, high productivity, and suitable for mass production. Most broaching machines only have a broach for the main motion of linear broaching, but no feed motion. In 1898, J.N. Lapointe of the United States manufactured the first mechanical transmission horizontal internal broaching machine. In the 1930s, a double-cylinder vertical internal broaching machine was manufactured in Germany, and a large flat side broaching machine for processing cylinder blocks was manufactured in the United States. In the early 1950s, continuous broaching machines appeared.

See lessThe Programmable Logical Controller (PLC) is also a general-purpose automatic control device based on the proud processor. It is also called a Programmable Controller (PC) or Programmable Machine Controller (PC). Programmable Machine Controller, referred to as PMC), is used to complete various logical operations and sequence control of CNC machine tools, such as machine start and stop, workpiece clamping, tool replacement, coolant switch and other auxiliary actions. The PLC also accepts instructions from the machine tool operating panel: on the one hand, it directly controls the actions of the machine tool; on the other hand, it sends related instructions to the CNC for processing control and creation. The PLC in the CNC system has a built-in type and an independent type. The internal I type PLC and CNC are combined and designed, also known as the integrated type, which is a part of the CNC; the independent type PLC is produced by an independent professional factory, also known as the exterior type.
The operation of the CNC machine tool is realized through the man-machine operation panel, which is composed of the CNC panel and the machine tool panel.
The numerical control panel is the operation panel of the numerical control system, which is composed of a display and a manual data input (Manual Data Input, referred to as MDI) keyboard, also known as an MD panel. The lower part of the display is often provided with a menu selection key, which is used to select a menu. In addition to various symbol keys, number keys, and function keys, the keyboard can also be set with user-defined keys. The operator can realize the system management through the keyboard and the display, and input, store, edit and modify the numerical control program and related data. During processing, the screen can dynamically display system status and fault diagnosis reports. In addition, the numerical control program and data can also be imported through the disk or the communication interface box.
The machine tool operation panel is mainly used for the operation of the machine tool in the manual mode, and the operation of the machine tool in the automatic mode. There are various buttons and selection switches on it, which are used for the start and stop of the machine tool and auxiliary equipment, the selection of processing methods, the selection of speed and override, etc.; there are also digital tubes and signal display. The operation panel of medium and small CNC machine tools is often integrated with the CNC panel, but there is a clear boundary between the two. The communication interface of the numerical control system, such as a serial interface, is permanent and located on the machine operation panel.

In industrial production, parts of various materials and shapes are needed, and the production of these parts requires stamping processing. Stamping processing is the production technology of using conventional or special stamping equipment to directly subject the sheet metal to deformation force and deformation in the mold, so as to obtain product parts with a certain shape, size and performance. Stamping processing can be divided into precision stamping and Ordinary stamping.
Precision stamping is a material processing method developed on the basis of ordinary stamping technology. It is achieved by improving the guiding accuracy, reducing the gap between the convex and concave dies, increasing the reverse pressure and the v-ring blank holder. Under the condition of the three-dimensional compressive stress state, the process of precision stamping or precision stamping and other forming processes can be realized to obtain precision stamping parts.
Precision stamping requires higher precision of stamping parts. In the process of processing and production, when stamping coils or forming, it is necessary to consider the appropriate technical matching of precision punches, molds, materials, lubricants, etc., which requires higher requirements.
Ordinary stamping does not require high precision of stamping parts, but it also has its specific market needs. The thickness of the substrate is thicker and does not require cutting, cutting, stretching and other processes. The stamping materials are plates, pipes, etc., and the product order is required. When it is not too big, ordinary stamping can meet the requirements.
In the production process of precision stamping parts, when stamping coils or forming, it is necessary to consider the appropriate technical matching of precision punches, molds, materials, lubricants, etc.
The other applies a 25% main punching pressure to the end surface of the product’s stripper, which is called back pressure. These three pressures do not interfere with each other, and the size of each pressure is synchronized with the forming, and must be suitable for processing requirements such as forming and blanking, and can be adjusted arbitrarily. In addition, the processing speed must also be adjusted according to the required conditions of the processing object for forming or punching. The structure of the mold is not only required to be simple and light, but also suitable for use.
When processing thick plates, for molds that are prone to deformation, there is no significant deformation due to the use of central support. Even when the workpiece is squeezed into the die during the blanking process, if the ejector retreats, the inside of the die is also supported by the center support. If a hydraulic piston is connected to the side of the ring gear pressing plate and the piston moves backward, the inner side of the die ring pressing plate is still supported by the central support, so the rigidity will not be destroyed at any time.
See lessThe difference between precision stamping and ordinary stamping lies in the requirements for stamping equipment and the accuracy of stamping parts required. If the precision of stamping parts is required to be high and the quantity of stamping parts is large, you can choose to use precision stamping. On the contrary, if the precision of stamping parts is not required to be high, and the stamping is made of ordinary sheet material, you can choose ordinary stamping. This needs to be based on your own The stamping features are selected.
